No problem. Have just been getting help from a guy in Japan who seems to know a lot about gobies.

It's looking like they're all Vanderhorstia species. The first one seems to resemble a goby that's spotted often in Bali, commonly referred to as a "spangled shrimp goby" (photos show up with a google search). The second might be V. lanceolata. Not too sure about that ID though. The third seems to be V. ornatissima.
